> Don't mean to brag but it took the 12 year old me less than an afternoon (armed with a CISCO book) to understand IPv4 syntax/routing/ARP/DHCP + whatever and roll it out to my 2 computers lan. Nothing about that is different for IPv6 for your 2 computer lab. But did you understand how your LAN differs from the internet, how NAT works, all about port-forwards, firewall traversal and why some apps could traverse firewalls (UDP) and some ones not (TCP)? Or did that come later? IPv4 has tons of hidden complexities people conveniently forget exist when they lament how terribly inaccessible IPv6 "really" is.
